MAINTENANCE AND PLANTING OF PARKWAY TREES
The City Council is vitally interested in beautification of City parkways.
Public cooperation in helping to develop and maintain healthy and attractive
trees is encouraged.
MAINTENANCE OF PARKWAY TREES
The Parks, Beaches and Recreation Department will trim the parkway trees
on a rotation schedule. An effort will be made to trim most of the parkway
trees on a two year cycle. If the rotation trimming is completed in less
than two years, more frequent trimming will be done on certain trees and in
view areas. Public safety such as low branches and heavy foliage will be
given priority over view trimming. An effort will be made to trim parkway
trees on the Peninsula and parts of Corona del Mar during the fall and
winter due to heavy traffic during the summer. Trimming schedule will be
altered to avoid trimming streets with flowering street trees during their
blooming time. This will apply to streets having a large number of flowering
trees, not to one or two trees on a street.
TREE LIST
The Parks, Beaches and Recreation Commission has adopted an official tree
list which will be used by.the Parks, Beaches and Recreation Department to
determine species for planning purposes in all new subdivisions and
replacement in establishe4 parkways.
